Replace your code with this code

 Container(
    //child: IndexedStack(
      //index: _selectedIndex,
      //children: _items
    //)//_items.elementAt(_index),
    height: MediaQuery.of(context).size.height*0.25,
    margin: EdgeInsets.all(20),
    alignment: Alignment.topCenter,
    child: IndexedStack(
      index: _selectedIndex,
      children: [
        ElevatedButton(
          style: ElevatedButton.styleFrom(
            minimumSize: const
            Size.fromHeight(50)
          ),
          child: Text('SUBUH'),
          onPressed: (){
            Navigator.push(context,
            MaterialPageRoute(
              builder: (context) => halamansubuh(
              )
              ),);}),
        
              ElevatedButton(
                style: ElevatedButton.styleFrom(
                  minimumSize: const
                  Size.fromHeight(100)
              ),
                child: Text('ZUHUR'),
                onPressed: (){
                  Navigator.push(context,
                  MaterialPageRoute(
                    builder: (context) => halamanzuhur(title: 'halamanzuhur', desc: 'halamanzuhur',
                    
                    )
                    ));
                }
              ),
              
        ]
        ));
